“Production chemicals used in subsea applications have to be produced to a high specification of cleanliness, typically to better than NAS 8 (or the equivalent SAE AS4059 specification). This is because subsea injection systems typically terminate in narrow bore control valves that are prone to blockage by even the smallest particulates. Measurement of these production chemicals is challenging due to the components often being highly acidic, alkaline or aromatic hydrocarbon based and therefore typical devices are limited in application due to the elastomeric or metallurgical components. The Spectrex device has proved to be very robust and almost ubiquitous in being able to measure the cleanliness of a wide range of production chemicals. This has enabled Clariant Oil Services to adhere robustly to the BASICS standard of subsea injection chemical specification, due to be released as a new ASTM standard in the near future.”

Particle counting is a critical aspect of any machine conditioning program and there are many tools out there available to monitor and track the quantity and severity of the contamination, be it due to external contamination or machine wear.
The specific application and type of particles will often govern what is the best particle counting technique for the job at hand. The continuous cleanliness of a hydraulic system, for instance, is very critical and even very low levels of dirt ingress can clog actuators...

For my research work, which concerns separation of liquid/liquid dispersions, I selected the Spectrex PC2200. It covers the whole range of droplet sizes which are of interest, i.e. from 0.5 to 100 microns. The procedure for analysis is very simple and results are obtained in less than a minute. This makes the Spectrex instrument very handy for use in the lab as well as for field measurements (A portable model, PC-2300, is available).
Initially I faced some problems with dilution of my water samples using distilled...

Particle toxicity in various water samples depends on the mixture of toxicants in each sample. Toxicity values for different samples can be expressed using the new metric: Particle Toxicity.
Use of the Spectrex PC-2000 was the instrument of choice in enumerating the particle concentrations for the calculation of the particle toxicity of drinking-water and reference toxicant suspensions. Generation of Particle Size Distribution Graphics with the PC-2000 also provided information which characterized the particle...
